performance monitor event selection for e5500 does not include L2 cache misses?

[hv]

I'm looking at the performance monitor event selection in the e5500 for L2 cache hits/misses.

The event selection includes:

Com:113    L2 cache data hits

Com:115    L2 cache instruction hits

I don't see events for L2 cache misses?

Thanks!

Hello HV HVO,

You may use L2 cache accesses minus L2 hit cache accesses to estimate. There is Backside L2 Cache Data Miss and Backside L2 Cache Instruction hit ratio in Scenario tool.

Have a great day,

What’s Scenario tool? I’m not familiar with that.

Another question: when I used the Performance Monitor event for L2 cache castouts on the e5500, it always comes out to be 0. What does the L2 cache castout really use for?

Thanks!
